With these delicious long dark nights of winter come low tides, just perfect to come out for a walk and see what is revealed as the tide drops back.

Best of all is the chance to explore with nauralists who can help point out sea life and explain the natural history of the plants and animals you will see. Beach naturalists will be on hand for two night time low tide walks:

This Friday, from 8:30 to 10:30 p.m. Low tide will be -2.84 at 10:27 p.m.

February 8, from 8:30 to 10 p.m. Low tide is -1.66 at 9:27 p.m.

The program is free. Dress for cold, cold weather and wear boots, hats, gloves, layers and rain gear if it is wet. Of course have a good flashlight, head lamp or lantern.

You may sample the walk for just a little while, or stay for the entire excursion. The naturalists will leave at 10:30 p.m. and everyone must be off the beach by 11:30, per city of Seattle rules.
